Magnum Primers

Switching from Winchester LPP to CCI #350 Magnum primers for .45ACP 3.8 WST 200 LSWC. Some say reduce load a couple tenths. Thoughts?

Because Winchester LPP are for magnum or regular loads I think you will be just fine especially with that light charge.  I use both all the time with my target loads without any problems.

Russ, should not be a issue. Win primers consistantly give me around 50 extra fps on loads compared to std primers. CCI mag should be very close.

Thanks for these responses. My intuition was no change/problem but nice to have confirmation.

WST is hard to light so the magnum primers are a good choice. Your load is pretty light to start with

In the winter time do not change the load in the summertime go down a 0.1 gn.
